System and method for sending and receiving information of digital cable broadcasting |
摘要 |
Disclosed is a system and method for sending and receiving information of digital cable broadcasting, which comprises: a headend unit for assigning a packet identifier (PID) from within a range of PIDs to tables carrying data according to inclusion of service information (SI), constructing a transport packet (TP), and sending it using an MPEG communication method; and a receiving unit for receiving the TP from the headend unit, checking the PID of the TP to determine whether the TP includes SI, and determining how to process the TP depending on inclusion states of SI in the TP. The PID discriminates a TP including SI from a TP including other messages in transmission of MPEG-2 TPs from the headend unit to the receiving unit.
